摘要: In situ tensile tests at various temperatures, ranging from 25 to 750° C, were conducted on an austenitic–ferritic cast duplex stainless steel (CDSS) to investigate both the plastic deformation mechanisms and the effect of temperature on mechanical properties. A continual reduction in the mechanical properties, such as ultimate tensile strength (UTS) and yield strength (0.2% proof stress, σ 0.2), was found as the temperature increased. Fractographic analysis demonstrated that tearing topography surface (TTS) was more likely …
